The Inland Empire Utilities Agency (IEUA) was formed in 1950 to supply imported drinking water to the Chino Basin. Originally named the Chino Basin Municipal Water District, IEUA has been a leader in water supply planning and programs to protect the region’s vital water supplies for over fifty years. Smart water planning starts with water conservation. Every gallon of water saved within the Chino Basin translates into reduced demand for expensive imported water supplies. By being more efficient, our community will increase the reliability of our existing water supplies and reduce the cost of imported water purchases. IEUA’s goal is to save over 25,000 acre-feet of water over the next twenty years through conservation – that’s about 7% of our area’s current water use.
